[0046] The screen touch control method provided in the embodiment of the present application can be applied to various scenarios where the screen needs to be controlled. In the embodiment of the present application, the screen can be a large touch screen device, and the large touch screen device can be composed of several sub-screens.
[0047] The execution subject of the touch control method of the screen provided in the embodiment of the present application can be a control device of the screen. The control device can be connected to the screen, and the control device can also be connected to each ranging sensor. When the user needs to control the screen, the various steps of the touch control method of the screen provided in the embodiment of the present application can be executed by the control device, so that the screen can be controlled more conveniently.
[0048] See also Figure 1 , Figure 1 The present invention provides a flowchart of a touch control method for a screen according to an embodiment of the present invention. The touch control method for a screen according to an embodiment of the present invention may include steps S101 to S103, which are described in detail as follows:
[0049] In S101, first distance data between a target object in a preset touch space and each distance measuring sensor is obtained through a plurality of distance measuring sensors.
[0050] The distance measuring sensor may be used to obtain first distance data between a target object in a preset touch space and the distance measuring sensor. Exemplarily, the distance measuring sensor may be a time of flight (TOF) distance measuring sensor.
[0051] Each time-of-flight ranging sensor can obtain the first distance data in the following manner:
[0052] The time-of-flight ranging sensor may include a photon signal transmitter and a photon signal receiver. Based on this, the time-of-flight ranging sensor can transmit a photon signal to a target object in a preset touch space through the photon signal transmitter. After the photon signal flies to the target object, it will be reflected by the target object and can be received by the photon signal receiver. Based on this, the time difference between the first time and the second time can be obtained by obtaining the first time when the photon signal transmitter transmits the photon signal and the second time when the photon signal receiver receives the photon signal, thereby obtaining the first distance data.
[0053] Each ranging sensor can be arranged at a preset position, and the relative position of the preset position and the screen is fixed. In an optional implementation, each ranging sensor can be arranged at a fixed position on the screen, and illustratively, each ranging sensor can be arranged at the edge of the housing on the screen.
[0054] In this embodiment, the number of each ranging sensor can be three, so that by measuring the distance to the target object, the target object can be better located. The number of each ranging sensor can also be set according to actual needs, for example, greater than three, which is not limited here.
[0055] The preset touch space may be a virtual space determined according to the performance and parameters of each ranging sensor. When the target object is in the touch space, each ranging sensor may respectively obtain first distance data with the target object, and send the first distance data to the control device, so that the control device may respectively obtain the first distance data between the target object in the preset touch space and each ranging sensor. When the target object is not in the touch space, each ranging sensor may not be able to obtain the first distance data with the target object.
[0056] The target object may be a user's hand or a user's stylus or other object. The user may control the screen by placing the target object at a target position in the touch control space, or the user may control the screen by moving the target object in the touch control space.
[0057] See also Figure 2 , Figure 2 A schematic diagram of a target object controlling a screen in a touch space provided in an embodiment of the present application. Figure 2 As shown, the user can use his hand to gesture "ABCD" at the target position in the touch space. At this time, each distance sensor will obtain the first distance data between the hand and each distance sensor at each moment. Figure 2 In the embodiment, the touch space may be a rectangular space in front of the screen.
[0058] In an embodiment of the present application, the control device can obtain the first distance data between the target object in the preset touch space and the ranging sensor through each ranging sensor, thereby obtaining the first distance data between the target object in the preset touch space and each ranging sensor.
[0059] In a possible implementation, each ranging sensor may include a Fresnel lens. The Fresnel lens in each ranging sensor may be connected to a control device. The control device may change the touch space by controlling the angle of the Fresnel lens in each ranging sensor.
[0060] In S102, a target touch point on the screen is determined according to each piece of first distance data.
[0061] The relative positions of the screen and the plurality of distance measuring sensors are fixed.
[0062] In the embodiment of the present application, after the control device obtains the first distance data between the target object and each distance measuring sensor, the control device can determine the target touch point on the screen according to each first distance data.
[0063] In a possible implementation manner, the control device may first obtain a first correspondence between each first distance data and each touch point on the screen, and then determine the target touch point according to each first distance data and the first correspondence.
[0064] The first corresponding relationship includes the first distance data corresponding to each touch point on the screen. It should be noted that, since the touch space in the embodiment of the present application includes multiple contact planes, each touch point corresponds to multiple corresponding points on the contact planes, and the multiple first distance data corresponding to the corresponding points on each contact plane are different. Therefore, in the embodiment of the present application, each touch point can correspond to multiple first distance data.
[0065] In a possible implementation, the control device may determine the first corresponding relationship through steps a to c, as described in detail as follows:
[0066] In step a, the screen is divided into a plurality of first areas, and the touch control space is divided into a plurality of touch control planes parallel to each other, according to a preset positioning accuracy.
[0067] In this implementation, the control device may divide the screen into a plurality of first areas according to a preset positioning accuracy. Figure 3 , Figure 3 A schematic diagram of dividing a screen into a plurality of first areas is provided in an embodiment of the present application, such as Figure 3As shown, when the screen is rectangular, the control device may divide the screen into a number of small rectangles of the same size as the second area.
[0068] In addition, the control device can also divide the touch space into a number of parallel touch planes according to the preset positioning accuracy. Figure 4 , Figure 4 A schematic diagram of dividing a touch space into a plurality of parallel touch planes is provided in an embodiment of the present application, such as Figure 4 As shown, a touch plane can be divided into a touch space at a preset distance. It should be noted that the shape of the touch plane is the same as that of the screen, but the length and width of the touch plane can be different from the length and width of the screen. In addition, each touch plane can be parallel to each other.
[0069] In step b, for each touch plane, the touch plane is divided into a plurality of second areas, and a second corresponding relationship between each second area and each first area is determined; for each second area of the touch plane, second distance data of the training object when touching the second area is obtained by using a plurality of distance measuring sensors.
[0070] In this implementation, after dividing the first area and the touch plane, the control device can divide each touch plane into a plurality of second areas and determine a second correspondence between each second area and each first area. In the second correspondence, one second area can correspond to one first area.
[0071] Specifically, the control device may divide the touch plane into a plurality of second regions according to the characteristics of the target object and the training object. For example, when the target object and the training object are fingers, the touch plane may be divided into a plurality of second regions according to the width of the fingers.
[0072] It should be noted that the number of first areas can be the same as the number of second areas, and there is a one-to-one correspondence between each second area and each first area, and the shape of each first area is the same as the shape of each second area, but when the length and width of the touch plane are different from the length and width of the screen, the length and width of the first area are also different from the length and width of the second area.
[0073] After dividing the touch plane into a plurality of second areas, the control device may further respectively acquire, for each second area of the touch plane, second distance data of the training object when the training object touches the second area through a plurality of distance measuring sensors.
[0074] Specifically, the user can touch each second area of the touch plane through a training object, and after each touching of a second area, obtain the second distance data of the training object when touching the second area through a plurality of distance measuring sensors, thereby obtaining the second distance data corresponding to each second area in the touch plane.
[0075] The above method can be applied to each touch plane, so as to obtain the second distance data corresponding to each second area in each touch plane.
[0076] It should be noted that the training object can be a user's hand and a stylus. The difference between the training object and the target object is that the training object is used to enable the control device to obtain the second distance data corresponding to each second area in each touch plane, while the target object is used to be placed or moved in the touch space so that the control device can obtain the first distance data between the target object and each distance measuring sensor.
[0077] In step c, the first corresponding relationship is determined according to the second distance data corresponding to each second area on each touch plane and the second corresponding relationship.
[0078] In this implementation, after the control device determines the second correspondence between each second area and each first area, and obtains the second distance data corresponding to each second area on each touch plane, the control device can determine the first correspondence based on the second distance data corresponding to each second area on each touch plane, and the second correspondence.
[0079] Specifically, the control device can determine the first area corresponding to each second area on each touch plane according to the second correspondence, and determine the sub-correspondence of the second area according to the first area corresponding to the second area and the second distance data corresponding to the second area. It should be noted that each first area corresponds to a touch point.
[0080] Since the second distance data obtained above are obtained by training the object to touch the second area on each touch plane, in actual application, the target object sometimes does not touch each touch plane very accurately, but may touch the boundary between the touch planes.
[0081] Based on this, in a possible implementation, the sub-correspondence relationship of any second region can be determined through steps d to f, as described in detail as follows:
[0082] In step d, the error range is determined according to the distances between the touch planes.
[0083] In this implementation, the control device may determine the error range according to the distance between each touch plane.
[0084] In actual applications, the relationship between the distance between each touch plane and the error range can be determined based on a pre-trained error range prediction model stored in the control device. Specifically, the error range prediction model can be trained through a deep learning algorithm, so that the distance between each touch plane can be input into the error range prediction model to instruct the error range prediction model to output the error range according to the distance between each touch plane, so that the control device can obtain the error range.
[0085] In step e, the distance data range corresponding to the second area is determined according to the second distance data and the error range corresponding to the second area.
[0086] In this implementation, after the error range is determined, the control device may determine the distance data range corresponding to the second area according to the second distance data corresponding to the second area and the error range.
[0087] In step f, the sub-correspondence relationship of the second area is determined according to the distance data range of the first area corresponding to the second area and the distance data range of the second area corresponding to the second area.
[0088] In this implementation, after determining the distance data range corresponding to the second area, the control device may determine the sub-correspondence relationship of the second area according to the first area corresponding to the second area and the distance data range corresponding to the second area.
[0089] In the above manner, the sub-correspondence relationship of each second area can be determined, so that when the target object touches the boundary between each touch plane, the target touch point can be accurately determined, thereby improving the touch accuracy.
[0090] Through the above method, the sub-correspondence relationship of each second area is obtained, and then the control device can determine the first correspondence relationship according to the sub-correspondence relationship corresponding to each second area on each touch plane.
[0091] In the following, the second area S1 on the touch plane Q1 is taken as an example. The control device can determine the first area S2 corresponding to the second area S1 according to the second correspondence. Since the touch point corresponding to the first area S2 is S3, the control device can obtain that the touch point corresponding to the second distance data corresponding to the second area S1 is S3, thereby obtaining the sub-correspondence corresponding to the second area S1. The above method is applied to each second area of each touch plane, so that the sub-correspondence corresponding to each second area can be obtained, and then the first correspondence can be obtained.
[0092] The control device may store the first corresponding relationship in advance, so that after acquiring each first distance data, the target touch point may be determined according to each first distance data and the first corresponding relationship.
[0093] In S103, the screen is controlled according to the target touch point.
[0094] In the embodiment of the present application, after determining the target touch point, the control device can control the screen according to the target touch point.
[0095] In actual applications, the specific method in which the control device controls the screen according to the target touch point can be set according to actual needs and is not limited here.
[0096] It can be seen from the above that the touch control method of the screen provided in the embodiment of the present application can be applied to the control device of the screen, specifically including: firstly, using a plurality of distance measuring sensors, respectively obtaining the first distance data between the target object in the preset touch control space and each distance measuring sensor, and then determining the target touch point in the screen according to each first distance data, the relative position of the screen and the plurality of distance measuring sensors is fixed, and finally the screen is controlled according to the target touch point. Through the method of the present application, the user can control the screen in the preset touch control space through the hand or the stylus and other objects, so the screen can be controlled without touching the screen or holding a controller, which improves the convenience of controlling the screen.
